The adjustable butt plate 20 is made to slide onto the stationary attachment plate 10 with the mating vertical rail system 21 sliding onto the mating vertical rail system 16 for smooth up and down motion. It has a pocket for locking button 23 to receive a locking button 30 for locking the vertical motion of the adjustable butt plate 20 in any locking detent pocket 14 and is formed to the right geometry so the locking button 30 when inserted will not protrude. There is a retaining pin hole 26 that acts as a retainment device for a button retaining pin 24 to be inserted to capture the locking button 30. There is a button return spring 25 that pushes the locking button 30 into locking position around pivot rail 28. There is also a counter bore 27 that retains the end of the button return spring 25 in place. There is an ergonomical and comfortable contact face 22 that is where the user shoulders the weapon.

The adjustable butt plate 20 could have any shape locking button 30 and may use a round, hex or any variable shape cavity and locking mechanism and may use numerous spring or button return springs 25 and button retaining pin type 24 devices to pivot the button. It may vary in the ergonomic and comfortable contact face 22 depending on the end users shape required. The mating vertical rail system 16+21 can be made of any shape or size that fits into the body of the adjustable butt plate 20. The outside shape can vary widely depending on the existing buttstock 40 its attached to or the shape of the buttstock 50 its being incorporated into. It could be made from any plastic, wood or metal with any type of manufacturing process such as plastic injection molding, molding, machining, casting ect.

D. Locking Button

The function of the button is to activate or deactivate the lock so the Adjustable Butt Plate can move vertically in a fast manner. As described briefly the locking button 30 sits in a pocket for locking button 23 placed in the pocket for locking button 23 of the adjustable butt plate 20 is retained by a button retaining pin 24, it pivots on a small pivot rail 28 and the button retaining pin 24. It has a knurl for grip on finger 31, a hole for retaining pin 32 for the button retaining pin 24 to slide into, a male locking tab 33 to lock into locking detent pocket 14, a hinge rail 34, a spring retaining boss or pocket 35 that is an internal spring retention feature and forms to the outer shape of the adjustable butt plate 20 as to not snag.

The locking button 30 may vary in shape and size as well as the way it locks to the locking detent pocket 14 and the way it pivots on the hinge rail 34. It could be a round shape, rectangular or any variation in between. The knurl for grip on finger 31 may be straight, cross hatched, diamond, indentation or any other means of non-slip surface. The outside shape can vary widely depending on what the existing buttstock 40 is attached to or the shape of the buttstock it's being incorporated into 50. It could be made from any plastic, wood or metal with any type of manufacturing process such as plastic injection molding, molding, machining, casting ect.

E. Existing Buttstock

This is the existing buttstock that the whole adjustable buttstock would attach to. The existing buttstock is the piece that the Adjustable Buttstock Assembly would be mounting to. Could be mounted on a gun or separated by removing it from the gun or rifle.

The existing buttstock could be any shape or size and could be made of many types of material such as but not limited to, plastic, wood or metal.

F. One Piece Stock

This would be a buttstock that would have the stationary attachment plate molded into the end as one unit. The one piece stock could comprise of the stock that fits onto the rifle and the stationary attachment plate incorporated into one unit. The one piece stock could be any shape or size that works for the gun it is being put on to and could be made from but not limited to, plastic, wood, carbon fiber or metal.

G. Connections of Main Elements and Sub-Elements of Invention

The stationary attachment plate 10 bolts to an existing buttstock 40 with mounting screws 13 through screw holes 1+2, 11 and 12 as illustrated in FIG. 5. The adjustable butt plate 20 slides its mating vertical rail system 21 onto the stationary attachment plate 10 mating vertical rail system 16. The adjustable butt plate 20 is prevented from sliding off the end of the stationary attachment plate 10 by the end of travel screw 15 that has an end of travel screw hole 17 in the stationary attachment plate 10. The locking button 30 fits into a pocket for locking button 23 on the side of the adjustable butt plate 20 and is captivated by button retaining pin 24 that slides into retaining pin hole 26, as well has a button returning spring 25 that is retained at one end by a counter bore 27 on the adjustable buttplate 20 and on the other end by the spring retaining boss or pocket 35. The button return spring 25 pushes the locking button 30 up on the knurl for grip on finger 31 end of the locking button 30 so that the male locking tab 33 will be engaged normally within the locking detent pocket 14. When the locking button 30 is pressed down on the knurl for grip on finger 31 it will pivot on the hinge rail 34 and pivot rail 28 around button retaining pin 24 and disengage the male locking tab 33 from the locking detent pocket 14 and allow the adjustable butt plate 20 to slide freely up and down vertically on stationary attachment plate 10.

H. Alternative Embodiments of Invention

A variation of the stationary attachment plate 10 could be that the Stationary attachment plate 10 and the existing butstock 40 could be molded as one piece, then the adjustable but plate 20 would slide onto the end of the now one piece buttstock 50 attachment plate as described in FIG. 3 number 50. The locking button 30 may be in a different shape, round, triangle ect and may use different means of locking instead of the male locking tab 33 such as a pin or a clamping device and could be a variety of shapes and sizes. The stationary attachment plate 10, adjustable butt plate 20 and locking button 30 may change shape and size depending on the buttstock 40+50 that they are being made for or incorporated into. The Locking Button 30 may have a boss or counterbore to retain the button return spring 25 onto the Locking button 30 as well as being raised up or having a boss underneath the knurled for grip on finger 31. The end of travel groove 29 and the end of travel screw 15 may be on either the Stationary attachment plate 10 or the Adjustable butt plate 20. The outside profile shape may change depending on the shape of the buttstock it is being attached to. The ergonomic and comfortable contact face 22 may vary depending on the shape of the shooter, shoulder, or body armor it will be fashioned for. All the individual parts may be manufactured in several fashions including but not limited to plastic injected molding, spin casting, sand casting, metal injection molding, 3D printing, die casting and machining. Any or all parts could be made from plastic, metal, aluminum, wood, carbon fiber, composites natural or man-made.

I. Operation of Preferred Embodiment

After installation of the Adjustable Buttstock assembly, FIG. 1, to the existing buttstock 40 with the two mounting screws 13 the user would push the locking button 30 on the knurl for grip on finger end 31 of the locking button 30 that would pivot on the hinge rail 34 and button retaining pin 24 thus disengage the male locking tab 33 from the locking detent pocket 14, at that point the user would slide the adjustable butt plate 20 vertically to a position they think would be ergonmic and comfortable then letting off the locking button 30 that would allow the button return spring 25 to push up on the knurl for grip on finger 31 end of the locking button 30 re-engaging the male locking tab 33 with the locking detent pocket 14 thus locking and preventing any more vertical movement between the stationary attachment plate 10 and the adjustable butt plate 20. This adjustment can be made in seconds allowing for many applications such as multiple people using the same weapon on any given day with different shooting stances and body types allowing more comfort, better line of site without tilting head and creating more engagement between the end of the buttstock and the users shoulder resulting in a faster more accurate shot. Another application could be one user that would be moving between stances or shooting positions, standing, kneeling, squatting, prone position or any shooting position and would need to adjust the butt plate in higher or lower manner fast as to maintain good contact between the buttstock end and shoulder, at the same time providing the proper elevation of the weapon as to see down the aiming device such as iron sites, scope, red dot or any gun sights without stretching or tilting head for a fast accurate shot.
